@StoryZen, it's absolutely worth it.
There are moments of true beauty when you offer your kindness to others. Sure, it might get shrugged off by many, but sometimes, all it takes to change a life is a single moment of compassion. Sometimes, you might not even realize that moment changed a person's life.
It might not fix everything, but our capacity for empathy and kindness is a beautiful thing.
Just don't let yourself get taken advantage of or sacrifice your own health.
